well, the rams depth chart list him behind Brown

Donnal has more size than Blythe.
I'd lean towards Donnal, but Kromer has the group playing well together, particularly Brown who hasn't been the problem. If you watching the way I do? I don't want to see my right guard. Honestly, I'd guess Donnal, even with his larger frame, might pull better than Jamon.

And just following along; these guys, Blythe, and Donnal, know each other well. Played on the same Iowa team, right?
